I wonder how many of these fall into the following categories:
1. The mined the coins themselves back when it was cheap to mine, or bought them when they are cheap. They are not actually much worse off then before they got into Bitcoin.
2. They put a lot of money into acquiring those Bitcoins. They are going to actually end up a significant fraction of that $600k worse of than when they started. However, they have millions of dollars or dollar equivalents elsewhere, and this loss is not really going to impact their lifestyle in any noticeable way.
3. They put a lot of money into acquiring those Bitcoins, and are going to end up a significant fraction of that $600k behind where they started. That represents a significant fraction of their wealth, and it will impact future plans to live a more extravagant lifestyle, but it won't knock them down to a lower class. They'll keep living where they live, and buying the same kind of luxuries they currently buy.
4. Similar to 2 and 3, but they had most of their wealth in this. They may have to move down a class or two on the social/financial ladder.
5. Similar, but they had so much of their wealth in this that "ruined" would be an accurate description. They basically have to start over financially.
